简要地介绍金刚石工具在切割过程中的磨损状况以及影响金刚石工具寿命的几个主要的因素。详细地介绍金刚石颗粒经过表面金属包渗处理后各种性能变化及检测结果，并对未经包渗处理的金刚石颗粒及包裹金属Ｗ、Ｔｉ的金刚石颗粒作ＴＧ－ＤＴＡ热分析，试验结果说明了金刚石颗粒经过金属表面包裹处理后，不仅极大地提高了胎体对金刚石的润滑性，而且提高胎体对金刚石的粘结强度，还提高金刚石的抗氧化能力，达到改善金刚石工具使用性能的目的。
Briefly introduce the wear status of diamond tools in the cutting process and the main factors affecting the life of diamond tools. The characteristics of diamond particles after infiltrating the surface of the diamond particles are introduced in detail. The results of the TG-DTA analysis show that the diamond particles without inclusions and the W, Ti-coated diamond particles are TG- Diamond particles wrapped by metal surface treatment, not only greatly improves the carcass of diamond lubricity, but also improve the bonding strength of the matrix of diamond, but also improve the diamond’s antioxidant capacity, to achieve the purpose of improving the performance of diamond tools.
